How to Make Sausage & Egg Keto Breakfast Casserole
Step 1: Preheat the Oven
Preheat your oven to 375° Fahrenheit. Lightly grease your baking dish, then layer the spinach leaves in the bottom along with the white parts of the scallions and chopped parsley. Set this dish aside as you prepare other ingredients.
Step 2: Cook the Sausage
In a large skillet over medium heat, cook the breakfast sausage until it is browned and crumbled. Stir often while cooking, breaking the sausage into small pieces with a spatula or wooden spoon.
Step 3: Whisk the Egg Mixture
While the sausage is cooking, take a large mixing bowl. Whisk together the eggs, heavy cream, garlic powder, salt, and pepper until fully combined. Once mixed well, gently fold in the freshly shredded cheddar cheese.
Step 4: Assemble the Casserole
Layer the cooked sausage on top of the spinach leaves in your baking dish. Pour the egg mixture evenly over the sausage so that it distributes well across the entire dish.
Step 5: Bake It Up!
Place your assembled baking dish in the preheated oven. Bake for about 20 to 25 minutes or until the casserole is firm and eggs are cooked through. Once done, remove from oven and slice into 12 squares. Garnish with green parts of scallions or additional shredded cheese if desired before serving warm.
